| | USGS Photo Glossary: Littoral cone |
 | | A cone of lava fragments built on the surface of a lava flow pouring into a body of water, usually the sea, is called a littoral cone ("littoral" refers to a shoreline). |
 | | Lava entering the ocean heats and boils seawater, often generating steam explosions that hurl tephra onto the shore, including spatter, bombs, blocks, ash,, lapilli, and, rarely, limu. |
 | | Once thought to be exclusively created by `a`a flows, many littoral cones have been observed recently on the surface of pahoehoe flows at Kilauea Volcano. |
